Product Line Details: Centric Premium Semi-Loaded Disc Brake Calipers

The Centric Premium Semi-Loaded Disc Brake Calipers line provides a balance between fully loaded and basic caliper assemblies. This semi-loaded caliper includes essential components such as the mounting bracket, abutment clips, and bleeder screw, but excludes pads and mounting hardware. This design allows for easier customization and replacement while maintaining high-quality materials like aluminum casting and phenolic pistons for heat resistance and durability.

Technical Specifications and Features

This floating disc brake caliper features two phenolic pistons with a diameter of 44.5 mm, which help reduce heat transfer to the brake fluid and improve overall braking performance. The caliper’s aluminum casting material offers corrosion resistance and weight savings compared to traditional cast iron. The inlet fitting uses a banjo style with an M10x1.0 thread diameter, compatible with standard brake lines on GM full-size trucks and SUVs. Included components such as the mounting bracket and abutment clips simplify installation, while the gray finish provides a clean, factory-style appearance.

Installation Notes and Tips

Ensure the mounting bracket included with this caliper is properly installed, as it is required for correct fitment. Although mounting hardware and brake pads are not included, use OEM or compatible parts to complete the brake assembly. Bleeder screw is included to facilitate proper brake fluid bleeding during installation. Verify inlet thread size (M10x1.0) matches your vehicle’s brake line fittings before installation.
